Can you freeze whipped icing or icing that comes out of the cans to make cake decorations?
if you are trying to make the decorations ahead of time to put on later, then I woudl say you could. The whipped icing will defrost after taking it out of the freezer though. If you are trying to decorate an ice cream cake, I would not freeze the icing. You ice the ice cream cake with ice cream….partially melted. Then you have to refreeze the iced ice cream cake for like 30 minutes until it’s good an hard again. Then come back with the whipped icing to decorate, but do it fast…like within 10 minutes! if not, you’ll have to refreeze the cake halfway through decorating.
